http://www.cuda-challenger.com Lots of good info there. Definately check to see if it has the original hurst shifter in it. 7180 should be stamped on the reverse lever. They are getting hard to find and kind of pricey as well. Car has the standard 8 3/4 rear end. At least it has the correct 4 speed pedals in it. 70-71 had the smaller pedals and 72-74 had the larger ones. If you get the car, take that chevrolet alternator and bracket off, lol, and replace it with the correct chyrsler pieces. I would guess a fair price would be in the 18-26K range. 70 challengers are very desirable, and it looks like most of the important pieces are there.
